BUCKLE FOR Tuo-STRAPS.

SPECIFICATION forming part of Letters Patent N 0. 697,543, dated April 1 5, 1902.

Application tiled May 1, 1901. Serial No. 58,291. (No model.)

.T0 all whom it muy concern:

Be it known that LWILLIAM I-I. ROSE, a citizen of the United States, and a resident vof Bemidji, in the county of Beltrami and State of Minnesota, have invented a new and Improved Buckle for Tug-Straps, of which the following is av full, clear, and exact description.

This invention has for its object to provide a novel, simple, and durable buckle that affords a reliable attachment .for the end of a t1ace.,or tug-strap upon hames of a harness, is convenient in adjustment to connect or release the strap, and which will avoid bending the strap or trace at the point of connection, thereby reducing injurious wear to which such straps are ordinarily subjected.

The invention consists in the novel construction and combination of parts, as is hereinafter described,and defined in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of the buckle, shown connecting a hame-bar and tug-strap. Fig. 2 is a longitudinal sectional view substantially on the line 2 2 in Fig. 1, and Fig. 3 is a transverse sectional View substantially onV the line 3 3 in Fig. 1.

The tug-strap 10, of which an end portion is shown, in complete form lnay be of any suitable length and, as usual, be formed of a plurality of plies of harness-leather to render it strong enough for efcient service.

The improved buckle comprises the following details of construction: A frame consisting of an elongated base-piece 1l, of such proportionate width as will adapt it to conform with the breadth of the strap 10, is provided with two similar side flanges 11, that are integrally joined thereto, and at one end of each ange an ear 11`D is extended beyond the adjacent end of the base-piece. The base-piece ll may have an aperture ct formed therein between its ends to lighten it, and the corners of the flanges 11a at their ends opposite those terminating in the ears 1lb are preferable rounded, as shown. A transverselocking-bolt 12 is inserted laterally through alined perforations formed centrally in the ears 11b,

n the ton gue-plate.

and upon the locking-bolt one end of a tongueplate 13 vis detachably secured, as follows: A tubulation b is formed on the end of the tongue-plate 13, of sufficient diameter to loosely receive the body of the bolt 12, that also passes through the ears 11b, as before mentioned. The tongue-plate 13 is of suflcient length to extend near to the rounded ends of the flanges l1, and at its extremity, which in service is adjacent to said ends, a tubulation c is thereon formed. y

Two opposite perforations are formed in the side anges l1, through which a pintlerod 14 is inserted, which also passes through the tubulation c, and said rod is secured by its ends in the lianges, whereby the end of the tongue-plate 13 that is farthest from the locking-bolt 12 is held to rock upon the buckleframe.

The tongue-plate 13 may with advantage be curved or bent down between the tubulations b c, so as to dispose the body thereof close to the strap 10, so as to bear thereon when the latter is introduced within the buckle-frame for connection therewith, and from the lower surface of the tongue-plate preferably two studs 15 are projected, which may be secured to the tongue-plate or formed integral therewith.

,It is to be understood that I may prefer in some cases to employ but one stud 15, which obviously would be positioned centrally of Generally, however, it is found advantageous to provide two studs 15, that are suitably spaced apart and have sufficient length to project loosely down through like spaced perforations e, formedy in the baseplate 11, as shown in the drawings.

The hame-bar 16 (shown in part) may be of anyapproved construction. Preferably, however, the wooden body thereof is reinforced on one side with a metal plate 16, and oppositely from the reinforce-plate a stiifeningblock 16b is bedded in a recess formed to receive it in the hame proper.

Two eyebolts 17 have their perforated heads 17 imposed upon the outer sides of the ears 11b and are thereupon held by the locking-bolt 12, which passes through the heads of the eyebolts and also through the ears 11b and through the tubulation b, as before explained, said bolt being removably held in IOO place by a head and nut on the ends of the same, as indicated in Fig. 1.

The bodies of the eyebolts 17 pass through spaced perforations formed in the hame-bar, reinforcing-plate, and the stiffening-block thereon, and, as shown, spacing-ferrules 1S are mounted upon the eyebolts and positioned adjacent to the heads thereof, these serving to properly space the buckle-frame from the haine-bar, and thus permit a flexure of the joint between the hame-bar-and ears on l[he buckle-frame.

To adapt the tug-strap 10 for connection with the improved buckle, suitable perforations e are formed therein for passage of the studs 15 therethrough and into the perforations e in the base-plate 11. To connect the tug-strap with the improved buckle that is to receive it, the tongue-plate 13 is released from the bolt 12 by removal of the latter from the tubulation l), so that the tongue-plate may be rocked `upon the pintle-rod 14 into the position indicated by dotted lines in Fig. 2. The tug-strap 10 may now be freely introduced endwise below the pintle-bolt and tubulation o, and the perforations e are relatively positioned so that the reversed rocking movement for disposal of the tongue-plate,as shown by full lines in Fig. 2, will permit the passage of the studs l5 through the perforations c in the strap and also through the alined perforations e in the base-plate 11. The lockingbolt12 is now replaced in the ears 11" and tubulation b, as well as in the heads of the eyebolts 17, and it is secured against accidental displacement by engagement of the nut on its projecting end. Hence if the pair of tugstraps necessary for a single harness are each provided with the improved buckle connections said tug-straps will be securely but detachably connected to the hames of the harness.

The pressure of the tongue-plates 13 upon the tug-straps 10 above the studs 15 produces frictional contact between the buckles and the tug-straps, so that the pulling strain is transmitted from the hames to the buckleframes and thence to the tug-straps in a manner that will prevent an injurious rubbing wear of the latter, which is incurred in use of tug-strap connections as usually constructed.

Having fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination with a frame comprising a base-plate and spaced flanges thereon, of a tongue-plate pivoted at one end between said anges, and detachably secured at the other end thereof bya transverse bolt, and a stud projecting from the tongue-plate through a perforation in the base-plate.

2. The combination with a base-plate having spaced anges at the sides thereof and spaced perforations in said base-plate, of a tongue-plate having a tubulation at each end, a pivot-rod engaging one of said tubulations and fixed in the spaced anges near one end thereof, ears on the opposite ends of the anges, having alined perforations, and 'abolt having engagement with the ears and also With the remaining tubulation on the tongueplate.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

YV ILLAM Il. ROSE.
